LAV Filters (aka LAVFSplitter) is a multi-format media splitter/decoder that uses libavformat (the demuxing library from ffmpeg) to demux all sorts of media files. MKV/WebM, AVI, MP4/MOV, MPEG-TS, FLV, OGG are tested and will be registered for. Other formats can be tested using GraphStudio. H264, VC-1, MPEG4-ASP (Divx/Xvid), VP8 have been tested and are working well. DTS, AC3, TrueHD, MP3, Vorbis have been tested. Subtitle Support. Stream Switching.

@ Post by prijatelj.v: The crashes / issues you describe are the result of interferences/crack ups in the graph creation process. Before installing Lav, make sure Haali is deinstalled properly, also deactivate the internal filters of your softwareplayer for the formats you want to split/decode with LAV. In the LAV options theres an "Input formats" tab, you can select Raw LPCM-audio as well. To avoid a messed up graph building, set everything to LAV, do not use any further postprocessing filters.
You can provide yourself much better/faster performance than with tha Haali setup (its 6 years old, no bugfixes/updates), LAV is constantly improved by its developer Nevcairiel (THX btw :). For guides /troubleshooting I strongly recommend checking out the Doom9 Forum, the Lav- and other software developers post there and are very kind providing profound help and tipps :)

This is a major release in my opinion. Although the changelog contains few update information, it actually has numerous small updates included within since the last stable version. This version seems faster than the previous ones. LAV getting better with time. We may have to ditch Haali Media Splitter in coming days. LAV splitter is going to take over ;)
Thanks devs for this package!

LAV Audio goes out of sync when connected to other ASF splitters, such as the GDCL WMV/WMA Parser. Besides, the MPEG-4 ALS decoder again has the problem that was fixed in revision 0.50.5-xxxxxx (it consumes 100% of the CPU-time on a Pentium-4, and freezes MPC-HC if the internal Audio Switcher is enabled).

Works great with very smooth video on my old pentium pro PC with Nvidia card. I have had problems with the LAV Audio decoder on 6 channel AC-3 audio. Audio volume changes seem exaggerated when audio goes from soft to load. This problem is rare and is not noticeable on most audio tracks so it's not a big problem but I have found that Divx decoder does not have the same problem.
